change the resolution when going fullscreen.

bcad1b813a xwayland: Add xwlVidModeGetCurrentRRMode helper to the vidmode code
crtc->mode reflects the mode set through the xrandr extension, once we
add support for also changing the mode through the vidmode extension this
will no longer correctly reflect the emulated resolution.

Add a new xwlVidModeGetCurrentRRMode helper which determines the mode by
looking at the emulated_mode instead.

Likewise add a xwlVidModeGetRRMode helper and use that in
xwlVidModeCheckModeForMonitor/xwlVidModeCheckModeForDriver to allow any
mode listed in the randr_output's mode list.

This is a preparation patch for adding emulated mode/resolution change
support to Xwayland's XF86 vidmode extension emulation.

44e1c97ca6 xwayland: Pretend we support viewport in vidmode
Some games (namely openttd) will raise an XError and fail with a
BadValue if their request to XF86VidModeSetViewPort fails.

Support only the default zoom and viewport, fail for everything else.

6070a749d9 xwayland: add partial xvidmode extension support
Older games (mostly those based on SDL 1.x) rely on the XVidMode
extension and would refuse to run without.

Add a simple, limited and read-only xvidmode support that reports the
current mode used so that games that rely on xvidmode extension can run
on XWayland.
